Mojo struct

QueuedTileScheduler

@register_passable(trivial) struct QueuedTileScheduler[tile_shape: UInt32, num_heads: UInt32, /, decoding: Bool, num_ctas: UInt32 = H100.sm_count, schedule: MHASchedule = MHASchedule.DEFAULT]

If decoding == False, then num_heads is q_num_heads. If decoding == True, then num_heads is kv_num_heads.

  • gidx_ptr (LegacyUnsafePointer[UInt32, address_space=AddressSpace.GLOBAL]):

Methods

__init__

__init__(gidx_ptr: LegacyUnsafePointer[UInt32]) -> Self

get_current_work_info

get_current_work_info[ValidLengthType: OptionalPointer, //](self, ts: MHATileSummary[ValidLengthType], state: MHATileState) -> WorkInfo

Returns:

WorkInfo

advance

advance[ValidLengthType: OptionalPointer, //, producer: Bool, sync: MHASchedulerSynchronization = MHASchedulerSynchronization.DEFAULT](self, ts: MHATileSummary[ValidLengthType], mut state: MHATileState, pipeline_idx: UInt32) -> OptionalReg[SeqInfo]

The parameter func must return a Bool indicating whether the WorkInfo arg is valid. This function returns whether the current idx corresponds to a valid WorkInfo. Note that if MHASchedulerSynchronization is NONE, then we assume it is only called by thread_idx.x==0.

Returns:

OptionalReg

grid_dim

static grid_dim(batch_size: UInt32, max_num_prompt_tiles: UInt32) -> Tuple[Int, Int, Int]

Returns:

Tuple

initial_state

initial_state[ValidLengthType: OptionalPointer, //](self, ptr: LegacyUnsafePointer[UInt32, address_space=AddressSpace.SHARED], tile_summary: MHATileSummary[ValidLengthType]) -> MHATileState

Returns:

MHATileState

unsafe_seq_info

unsafe_seq_info[ValidLengthType: OptionalPointer, //](self, ts: MHATileSummary[ValidLengthType], state: MHATileState) -> SeqInfo

Returns:

SeqInfo

get_type_name

static get_type_name() -> String

Gets the name of the host type (the one implementing this trait).

Returns:

String: The host type's name.

get_device_type_name

static get_device_type_name() -> String

Gets device_type's name.

Returns:

String: The device type's name.
